Re: 6v generater vs 6v alternator
I will try to draw a diagram of what I did.

I bought this kit to rebuild my 10SI as a 6V+ alternator. It worked great and has been on the car nearly a year with no trouble. I have no connection to the seller, just a happy customer. Micheal in Bismarck, ND |

Re: 6v generater vs 6v alternator
I just bought a powergen 6v positive ground alternator for my 29 phaeton.
Other than connecting a ground cable to the rear housing cover bolt, the installation instructions say to run a "charge"wire to the negative battery post from the terminal on top of the alternator. Can this attach to the starter switch bolt or needs to run further back to the actual battery post? Also where do the horn and headlamp wires connect? I called tech support and he said he was unfamiliar with model A wiring..... Thanks for your help! |

Ron, wire it like original (as alexiskai said).

I don't see in the pic the "charge" wire or separate ground that the instructions told me to do? I'd sure hate to fry something..... Thanks, Ron |

What's the part number for the alternator you bought? |

Re: 6v generater vs 6v alternator
Hope this helps. My PowerGen is grounded to the block and the block is grounded to the frame at the transmission.
Connect ground wire to either. Last edited by Y-Blockhead; 02-07-2023 at 01:48 AM. |

Re: 6v generater vs 6v alternator
Has anyone else installed what mfarley post42 did? It certainly is a way cheaper alternative to the new powergens, that I also use and like. Does this set up still use a cutout?

I think P.S. did a video explainer on the Delco alternator conversion. Alternators don’t use external cutouts. |

Re: 6v generater vs 6v alternator
How much is the “huge amp increase “ with the powergen, I don’t want the advertising amount, who has done on the car testing of real world output?
The ad states “stops dimming headlights “ — the first thing i noticed when i put in halogen bulbs is that the dimming at idle went away when the generator was not charging. If there is such a large increase in amperage what is the recommendation for increasing the wire size to handle the increased amperage of the charging system? |

Generally speaking, lead-acid batteries max out charging amperage around 25% of their rated Ah. So for example, the Optima Red is rated at 50 Ah, which means you could send it at most 12A before you'd start damaging it. Halogens might draw 10A. Sound the horn at the same time, that'll draw 5A. Now you're at what, 30A? To go any higher you'll need an electric heater or something else with a large current draw. So the wiring doesn't have to be sized to handle the full 60A output unless you reasonably expect to use that output somewhere. Powergen recommends 8-gauge wire, but you should assess your individual situation to determine the gauge you need. |

Re: 6v generater vs 6v alternator
I know the advertised output is not the same as real world, the cold output is a lot more than the hot output, and to make that output the power has to be transmitted from the crankshaft to the alternator shaft.
When I go to shows I rarely touch anything on cars that are on display, there is one weakness I have, it is touching alternator fans, with one finger pushing on the fan I have yet to find one that doesn’t easily slip on the belt, this is why I am asking if real world output on the car is being tested, I know from many years of working on more modern cars that when touching the alternator fan and having it easily slip on the belt that the car will have battery low charge problems. I f the wire is not good for the largest possible output someday the smoke will come out of the wire, if the battery is low on charge a alternator will put out whatever amps it can do up to its rating to make the voltage unless there’s other limitations like battery not willing to be charged or slippages in the power transmission I think there is room inside the flywheel for a permanent magnet alternator, probably enough to run electric air conditioner, have emergency power for house |

Re: 6v generater vs 6v alternator
Thanks guys for the clarification of operation and connections.I don't expect to ever need anywhere close to the max output as powergen claims. 8 gauge wire seemed excessive for a ground wire and to replace the existing original charge wire. I suppose they have to cover their rears on max output.
Powergen 82006 is what I bought. By the way, nice looking engine compartment! I'll install and report back... |

Will try and find a picture of the finished product for You. Since you are asking about this, I venture you are not into having your car be original per judging standards. Me neither! |
